Polar Star has a powerful engine of analysis and calculation that allows a wide range of sizes and capabilities:
or standard measures also according to IEC 61000-4-30 of V, I, P, Q, A, F, PF, THD%, instantaneous values / min / max / avg, absorbed and products, energy meters (kWh, KVA , kVAr) absorbed and generated;
- Harmonic analysis of 7 channels (3 voltages and 4 currents) up to the 31st order, with its graphical and numeric display;
- Extent of outages and network brownouts;
- Extent of the DIP (voltage drops);
- Extent of SWELL (Surge);
- Graphical display of TREND (trends over time) of 6 selectable sizes;
- Measuring energy in 4 time periods (tariffs) set;
- Automatic connection test to determine if the connections of the voltages and currents are correct;
- Customization of the user display, which can independently choose which values to keep under control
